Math question: What is the sum of all the even numbers between 1000 and 7000 that are divisible by both 3 and 7?

To solve this question, we need to find the even numbers between 1000 and 7000 that are divisible by 3 and 7. We can start by finding the smallest even number in this range that satisfies these conditions, which is 1102. From there, we can find the largest even number, which is 6966. Now, by applying the formula for finding the sum of an arithmetic series, we can calculate the number of terms, which is (6966 - 1102)/2 + 1 = 2933. With the formula for the sum of an arithmetic series, S = (n/2)(first term + last term), we can find the sum: S = (2933/2)(1102 + 6966) = 10,147,615. Therefore, the sum of all the even numbers between 1000 and 7000 divisible by both 3 and 7 is 10,147,615.

Math Question: Find the largest prime number smaller than 6907 that leaves a remainder of 1 when divided by 4, 5, and 9. Solution: To solve this problem, we can work backwards from 6907 to find the largest prime number that meets the given conditions. We start by checking if 6907 - 1 = 6906 is a prime number. However, 6906 is divisible by 2, so it's not a prime number. Next, we check 6906 - 1 = 6905. This number is also divisible by 5 (as it ends with 5 or 0), so it's not a prime. Continuing this process, we find that 6881 is divisible neither by 2, 5, nor 9, making it the largest prime number smaller than 6907 that leaves a remainder of 1 when divided by 4, 5, and 9.

The largest prime number smaller than 6907 that leaves a remainder of 1 when divided by 4, 5, and 9 is 6881.

Math question: What is the sum of the digits in the number 6907?

To find the sum of the digits in 6907, we add each individual digit together. The thousands digit is 6, the hundreds digit is 9, the tens digit is 0, and the units digit is 7. Add these digits: 6 + 9 + 0 + 7 = 22. Therefore, the sum of the digits in the number 6907 is 22.
